Product Description
The eight-slot Juniper Networks
®
EX8208 Ethernet Switch, part of the Juniper Networks
EX8200 line of Ethernet Switches, is ideal for aggregating access switches such as Juniper
Networks EX3200 and EX4200 lines of Ethernet switches deployed in campus wiring
closets and in data center top-of-rack applications. The EX8208 is also designed to
support 1-Gigabit and 10-Gigabit Ethernet server access in data center end-of-row chassis
deployments. In core applications, the EX8208 provides approximately 960 Mpps of high-
density, wire-speed 10-Gigabit Ethernet performance for the largest campus and data
center networks.
Customers can advance the economics of their network by leveraging the consistent
performance of the Juniper Networks EX8200 line of Ethernet switcheswire-speed line
cards, in conjunction with the EX4500, EX4200, EX3200 and EX2200 lines of Ethernet
switches and Juniper Networks Junos

operating system to reduce capital and operational
expenses across the network infrastructure.
EX8208 Ethernet Switch
The EX8208 switch includes an advanced set of hardware features enabled by Juniper-
designed EX-PFE2 ASICs and the carrier-class Juniper Networks operating system, Junos
OS, delivering the capabilities needed to support the high-performance networks of today
and tomorrow.
The EX8208 switch features eight dedicated line-card slots that can accommodate a
variety of EX8200 Ethernet line cards. Options include the following:
• EX8200-48T: a 48-port 10/100/1000BASE-T RJ-45 unshielded twisted pair (UTP)
line card
• EX8200-48F: a 48-port 100BASE-FX/1000BASE-X SFP fiber line card
• EX8200-8XS: an eight-port 10GBASE-X SFP+ fiber line card
• EX8200-40XS: a 40-port 10GBASE-X SFP+ / 1000BASE-X SFP line card
Fully configured, a single EX8208 chassis can support up to 384 Gigabit Ethernet or 64
10-Gigabit Ethernet ports at wire speed, or 320 10-Gigabit Ethernet ports in shared bandwidth
applications, delivering one of the industry’s highest 10-Gigabit Ethernet port densities.
Product Overview
The EX8208 modular Ethernet switch,
a member of the Juniper Networks
EX Series Ethernet Switches product
family, oers a flexible, powerful,
and modular platform that delivers
the performance, scalability, and
high availability required for today’s
high-density data center, campus
aggregation, and core switching
environments. With a total capacity
of up to 6.2 Tbps, the EX8208 system
provides a complete, end-to-end
solution for the high-performance
networks of today and into the future.
